In the context of globalization, intellectual property protection, especially patent rights, has become a core element for Japanese companies to maintain competitive advantages in international markets. As Japanese enterprises continue to expand into overseas markets, how to effectively plan international patent application routes, protect technological innovations, and avoid patent infringement risks has become an important issue that companies must address when formulating globalization strategies. The complexity of international patent applications lies in the differences in legal systems, market environments, technological competition, and application processes across different countries and regions. Therefore, a reasonable international patent application strategy can not only help companies protect their intellectual property but also enhance their international competitiveness.
This article will discuss in detail the key factors that Japanese companies need to consider in the global patent application process and propose a systematic international patent application route planning scheme. We will combine the latest trends and examples of global patent protection to help companies develop more effective international patent application strategies to ensure their long-term success in the global market.
Patent Protection Needs of Japanese Companies in the Context of Globalization
1.1 Patent Competition Landscape in the Global Market
In the context of globalization, patents have become not only a legal protection tool for technological innovation but also a strategic weapon for companies to participate in global competition. In recent years, the number of global patent applications has been increasing annually, especially in technology-intensive industries such as electronics, communications, semiconductors, and biomedicine, where patent competition has become increasingly fierce. According to the latest data, global patent applications reached over 3 million in 2023, mainly concentrated in the American, European, and Asian markets. This trend indicates that technological competition has shifted from regionalization to globalization, and if companies want to occupy a place in the global market, they must protect their technological advantages through international patent applications.
For Japanese companies, the pressure of patent competition in the global market is particularly evident. Taking the electronics and semiconductor industries as examples, Japanese companies have long relied on patent layout for their technological advantages in the global market. However, in recent years, with the rise of emerging economies such as China and South Korea, the number of patent applications in these markets has surged, bringing new challenges to the international patent layout of Japanese companies. Therefore, how to effectively apply for patents in these emerging markets has become an issue that Japanese companies must seriously consider.
1.2 Current Status and Challenges of International Patent Applications for Japanese Companies
Although Japanese companies have strong patent layout capabilities in the domestic market, they still face many challenges in the international market, especially in the process of cross-regional patent applications. First, when conducting international patent applications, Japanese companies are often affected by differences in patent systems in different countries and regions. For example, although both the United States and Europe are major global patent application regions, their patent application processes, examination standards, and legal frameworks differ significantly, adding complexity to Japanese companies’ international patent applications.
Secondly, Japanese companies also need to face patent infringement risks in different countries and regions in the international market. Due to differences in legal systems, market environments, and technological competition in the international market, Japanese companies are prone to patent litigation troubles when expanding overseas markets. Therefore, how to make reasonable risk predictions at the initial stage of patent applications and avoid potential infringement risks through effective legal layout is an issue that companies need to focus on.
Finally, Japanese companies usually face high cost pressures when conducting international patent applications. International patent applications not only include application fees but also involve translation, attorney fees, patent maintenance fees, etc. The accumulation of these costs often brings a significant economic burden to small and medium-sized enterprises. Therefore, formulating an international patent application strategy that balances cost control and patent protection is an urgent problem to be solved in the globalization process of Japanese companies.
1.3 The Necessity of Ensuring Global Protection of Technology
In the global market, the protection and innovation of technology are inseparable. If Japanese companies cannot effectively protect their technological innovations, it may lead to competitors gaining technological advantages through infringement or imitation, thereby weakening the company’s competitiveness. Especially in the current international market, where technology leakage and infringement occur from time to time, companies must take corresponding patent protection measures while developing technology to ensure that their technological advantages are not threatened due to insufficient patent protection.
On the other hand, international patent applications are not only a means of protecting corporate technology but can also create more business opportunities for companies. Through reasonable patent layout, Japanese companies can obtain more technology authorization opportunities in the international market, and even gain additional income through patent licensing and technical cooperation. This is undoubtedly an important strategic choice for companies that have leading technologies in the global market.
Key Elements in Formulating International Patent Application Strategies
2.1 Market Selection and Patent Layout Strategy
When planning the international patent application route, market selection is one of the key factors determining the success of the patent layout. Different markets have different patent application costs, legal frameworks, and technological competition environments. Companies need to choose the most suitable market for patent applications based on their product technology characteristics, market demand, and competitors’ patent layouts.
Firstly, companies need to prioritize countries and regions with huge market potential. For Japanese companies, European and American markets have always been the focus areas for technology export. As the world’s largest single economy, the United States has a well-established patent protection system and extensive market demand. Therefore, for companies with leading technologies, the patent layout in the US market is indispensable. The European market is known for its diverse patent system. Although the application cost is relatively high, the patent protection effect of the European market covers multiple countries. Therefore, for Japanese companies entering the European market, unified application for European patents can greatly simplify the patent application process.
In addition to traditional European and American markets, Japanese companies also need to consider patent layouts in emerging Asian markets. In recent years, regions such as China, India, and Southeast Asia have experienced rapid economic growth and strong technological demand. Especially in fields such as electronics, communications, and biomedicine, the number of patent applications in these markets has increased significantly. Therefore, when conducting international patent applications, Japanese companies cannot ignore the potential opportunities in these emerging markets.
Secondly, companies also need to evaluate their competitors’ patent layout situations. By analyzing competitors’ patent layouts, companies can better understand the technological development trends in the market and avoid overlaps or gaps in patent layouts. For example, companies can query the number and distribution of competitors’ patent applications in specific technological fields through patent databases, and then adjust their own layout plans based on competitors’ patent strategies to ensure that the company is in an advantageous position in technological competition.
2.2 Choice of Patent Application Routes
When planning international patent application routes, companies can choose different application paths, including single country applications, regional patent applications, and international patent applications. Each path has its advantages and disadvantages, and companies need to choose the most suitable application method based on specific situations.
Single country applications refer to companies directly submitting applications to the patent office of the target market. This method is suitable for companies that only focus on specific national markets. The application process is relatively simple, but if companies plan to enter multiple national markets, they need to apply separately in each country, which is costly and complex.
Regional patent applications refer to companies obtaining patent protection in multiple countries through a single application. For example, the European Patent Application (EPO) allows applicants to obtain patent protection in multiple European countries. This method not only simplifies the application process but can also effectively reduce application costs. However, the maintenance fees for regional patents are usually higher, and in practice, companies still need to maintain patents according to the legal requirements of each country.
The international patent application route is a global patent application conducted through the Patent Cooperation Treaty (PCT). PCT provides companies with a unified application platform, allowing companies to enter the patent examination procedures of multiple countries through a single application. This method greatly simplifies the process of international patent applications and gives companies more time and resources. However, PCT only provides an examination framework, and the final patent grant still depends on the patent offices of various countries. Therefore, companies need to complete patent applications in each country within the specified time.
2.3 Cost Control and Risk Management
The cost of international patent applications is a factor that companies cannot ignore when planning patent layouts. The cost of patent applications not only includes application fees but also involves translation fees, attorney fees, maintenance fees, etc. Therefore, how to reasonably control costs and avoid unnecessary expenses is an issue that companies need to focus on.
Firstly, companies can reduce costs by choosing suitable application routes. For example, for companies hoping to obtain patent protection in multiple national markets, they can choose to apply through PCT to simplify the application process and reduce the cost of repetitive applications. In addition, companies can prioritize patent applications in core markets based on market importance, avoiding wasting resources in countries with less market potential.
Secondly, risk management is also an important aspect that needs attention in the patent application process. In the international market, patent infringement and technology leakage occur from time to time. Companies need to avoid these risks through legal means and patent layout. By conducting risk assessments on the patent systems and competitive environments of target markets, companies can predict possible risks in advance and formulate corresponding response strategies. For example, in markets with higher technological infringement risks, companies can reduce risks by increasing the number of patents and expanding the scope of patent protection.
Practical Experience of Japanese Companies in International Patent Applications
As Japanese companies continue to expand their technological innovation steps in the context of globalization, international patent applications have become a key means to protect core technologies and enhance competitiveness. In the face of fierce competition in the globalized market, patents are not only a tool for technological protection but also an important weapon for companies to gain market share and establish industry standards. Japanese companies, especially those leaders in high-tech fields such as electronics, automobiles, and biomedicine, have begun to formulate special international patent application strategies to ensure their technological advantages and legal protection in the global market.
3.1 Case Analysis of Patent Layout by Well-known Companies

Sony’s patent application layout not only covers Japan but also widely covers major global markets such as the United States, Europe, and China. Careful study of Sony’s patent layout can provide valuable experience for other companies.
Sony’s international patent layout follows the principle of “core technology protection”. Sony first applies for patents in Japan to ensure that its innovative technologies can be legally protected at the earliest time point. Sony attaches importance to the timeliness of technological innovation, so its patent applications often accompany the simultaneous progress of technology research and development. Through this method, Sony can quickly incorporate its technological innovation results into the legal protection framework, avoiding imitation or misappropriation by competitors before the technology is introduced to the market.
After successfully obtaining patent rights in Japan, Sony then applies for patents in other major markets through the Patent Cooperation Treaty (PCT). PCT provides companies with a convenient international patent application channel. Sony uses this advantage to submit patent applications in multiple countries and regions such as the United States, Europe, and China through PCT. This strategy not only ensures the protection of its technological innovations in the global market but also greatly improves the efficiency and coverage of patent applications.
Through this two-step patent application strategy, Sony has maintained its technological leadership in the global electronics market. For example, Sony’s core technologies in products such as televisions, smartphones, and audio equipment have all obtained extensive patent protection worldwide through this strategy. In addition, Sony has also obtained additional sources of income through patent licensing and other methods, further consolidating its advantageous position in the electronics industry.
Another successful patent layout case is Toyota Motor Corporation. As one of the world’s largest automobile manufacturers, Toyota has a huge patent pool in the fields of electric vehicles and hybrid technology. Through its patent pool, Toyota not only protects its own technological innovations but also promotes technological progress in the entire automotive industry through patent licensing.
Toyota’s patent application strategy focuses on the fields of electric vehicles and new energy technologies. Facing the major trend of the global automotive industry’s transition to green energy, Toyota started large-scale patent application layout at the early stage of electric vehicle technology research and development. Toyota’s patent pool covers various core technology areas of electric vehicles, including battery management systems (BMS), electric drive systems, and electric charging infrastructure.
Toyota’s patent pool is not only used to protect its own technology but also promotes the formation of industry standards through patent licensing. For example, Toyota cooperates with other automobile manufacturers to jointly develop and promote hybrid technology through patent licensing. This strategy not only accelerates the market application of technology but also enhances Toyota’s technological influence in the global automotive market. Through extensive patent licensing, Toyota effectively reduces the risk of patent infringement and establishes solid technological barriers in markets of multiple countries.

(2) International Patent Application Strategy in the Biopharmaceutical Industry
The biopharmaceutical industry is a highly technology-intensive field with long research and development cycles and extremely high R&D costs. Therefore, patent protection is crucial for the survival and development of enterprises. The international patent application strategies of Japanese biopharmaceutical companies mainly revolve around drug development and biotechnology patents.
Due to the long life cycle of drugs, biopharmaceutical companies typically apply for patents in the early stages of product development to ensure that their innovative technologies are not threatened by competitors. For example, a large Japanese biotechnology company would first apply for patents simultaneously in major global markets through PCT during the initial stages of drug development. This approach ensures timely protection of drug patents in different markets and avoids competitors preemptively registering research results before the product launch.
Furthermore, patent portfolio management is particularly important in the biopharmaceutical industry. As drug technology involves multiple technological fields, companies usually establish patent portfolios to ensure comprehensive protection of their core technologies. For instance, when developing a new drug, a company would not only apply for patents on the chemical composition of the drug but also on related patents such as production processes, packaging forms, and dosage control. This patent portfolio strategy can form a powerful patent protection network, ensuring that the company’s innovative achievements are not easily circumvented.
(3) International Patent Application Strategy in the Automotive Industry
As one of Japan’s pillar industries, the automotive industry’s international patent application strategy mainly focuses on technical standards and technology licensing. With the global automotive market transitioning towards electrification and intelligence, Japanese automakers such as Toyota and Nissan ensure widespread application of their technologies in the global market through large-scale patent applications.
Japanese automakers have particularly extensive patent layouts in the field of electric vehicles. Taking Toyota as an example, the company has applied for numerous patents in technologies such as electric drive systems, hydrogen fuel cells, and battery management. Through these patent layouts, Toyota not only protects its technological innovations in the electric vehicle field but also promotes the formation of industry standards. For instance, Toyota’s hybrid power technology has been widely applied to major global automakers through patent licensing, forming industry standards and greatly promoting the popularization of technology.
Moreover, Japanese automakers also focus on establishing partnerships through patent licensing.
